Bug#920633: bumblebee: Entry 'Driver=nvidia' not added in bumblebee.conf after bumblebee installation

[Andreas Christ]

Package: bumblebee
Version: 3.2.1-19
Severity: important

Dear Maintainer,

I installed bumblebee on a fresh installation of buster on a Dell G3 3579 with
GTX1060 MaxQ following the instructions on https://wiki.debian.org/Bumblebee.
Before installing bumblebee, I had added i386 architecture.

Optirun then returned:

[ 1778.285793] [ERROR]Cannot access secondary GPU - error: Could not enable
discrete graphics card
[ 1778.285868] [ERROR]Aborting because fallback start is disabled.

In bumblebee.conf, I had to make the following changes:

[bumblebeed]
Driver=nvidia

[driver-nvidia]
PMMETHOD=none


Driver was empty before, and PPMETHOD was set to auto. I am not sure if the
latter setting is needed.

With these changes, optirun and primusrun work:

christ at CARTMAN:~$ optirun inxi -G
Graphics:  Device-1: Intel UHD Graphics 630 driver: i915 v: kernel
           Device-2: NVIDIA GP106M [GeForce GTX 1060] driver: nvidia v: 390.87
           Display: x11 server: X.Org 1.20.3 driver: modesetting unloaded:
fbdev,vesa resolution: 1920x1080~60Hz
           OpenGL: renderer: GeForce GTX 1060 with Max-Q Design/PCIe/SSE2 v:
4.6.0 NVIDIA 390.87


As I found a lot of reports about problems with bumblebee and tlp, I wanted to
mention that I do not have tlp installed.

Best regards,

Andreas Christ
